Answer:

Δ ABC Δ DEF

Step-by-step explanation:

Given:

W need to Prove Δ ABC Δ DEF

Solution:

Statement:                                                  Reason

                   a) Given

"While Constructing both the triangle the lines were made parallel."

DE ║ AB                            c) Construction of Δ DEF on to Δ ABC

" When the Lines are parallel then their corresponding angles are equal in measure."

∠A ≅ ∠ EDF and ∠C ≅ ∠ EFD d) Corresponding Angles of parallel lines

Now By AA similarity theorem which states that;

"When 2 angles of one triangle are congruent to corresponding 2 angles of another triangle then 2 triangles are said to be similar."

Δ ABC Δ DEF        b) By AA Similarity theorem.
